Step 1: Create a New Project

Getting started with Etap begins by creating a new project. After launching the software, users can start a fresh project and define the system parameters according to their requirements. This includes specifying project details such as system voltage levels, frequency settings, and engineering standards that will be used throughout the design process.

Once the project is created, Etap provides a graphical workspace where users can build a one-line diagram representing the electrical network. This visual representation serves as the foundation for all future analyses and simulations. Proper project setup ensures accurate calculations and reliable study results.

Step 2: Import Media / Setup

After creating the project, the next step is setting up the electrical system model. Users can manually add components such as transformers, generators, buses, circuit breakers, cables, motors, and protective devices. Each component can be configured with detailed electrical characteristics and operational parameters.

Etap also supports importing existing system data from various engineering databases and external sources. This capability significantly reduces data entry time and improves project accuracy. By carefully entering equipment specifications and ratings, users can create a realistic model that closely reflects the actual electrical system.

Step 3: Main Workflow (Editing, Design, and Analysis)

The primary workflow in Etap revolves around designing and analyzing electrical power systems. Engineers start by constructing the network model using drag-and-drop tools and then perform various engineering studies to evaluate system performance.

One of the most commonly used functions is load flow analysis, which helps determine voltage levels, power factors, and energy distribution throughout the network. Users can also perform short circuit studies to identify fault currents and verify equipment ratings. Additional analysis tools include transient stability studies, motor acceleration analysis, and harmonic assessments.

The intuitive interface makes it easier for both beginners and experienced engineers to navigate complex projects while maintaining accuracy and efficiency during system design and evaluation.

Step 4: Add Features (Effects, Tools, and Customization)

Etap offers an extensive range of advanced features that enhance electrical system analysis and optimization. Users can customize their projects with protective device coordination studies, arc flash hazard analysis, reliability assessments, and energy management tools.

Some of the most valuable features include:

• Load flow analysis
• Short circuit calculations
• Arc flash analysis
• Relay coordination studies
